Convenient synthesis of alkylhydrazides by the cobalt-catalyzed hydrohydrazination reaction of olefins and azodicarboxylates

Treatment of olefins with an excess of di-tert-Bu azodicarboxylate, an equimolar amt. of PhSiH3, and a catalytic amt. of a Co(III) catalyst afforded the Markovnikov hydrazide products, e.g., I, for a broad range of olefins, in good yields. [on SciFinder (R)]
